This is the E-flite BL15 Brushless Ducted Fan Motor. E-flite's BL15 DF Brushless Motor is an ideal choice for products such as E-flite’s BAe Hawk 15 DF and other similar sized ducted fan airplanes when using the purpose-built Delta-V 15 69mm EDF (EFLDF15). The motor will provide great performance in 68–70mm diameter fan units requiring a 28mm inrunner motor.
